Updated xorg-x11 packages that fix several integer overflows,various bugs, are now available for Fedora Core 4.

X.Org X11 is an implementation of the X Window System,which provides the core functionality for the Linuxgraphical desktop.

Several integer overflow bugs were found in the way X.OrgX11 code parses pixmap images. It is possible for a userto gain elevated privileges by loading a specially craftedpixmap image. The Common Vulnerabilities and Exposuresproject (cve.mitre.org) has assigned the name CAN-2005-2495to this issue.

Additionally, this update contains:

- Support for some newer models of Intel i945 video chipsets.

- A fix for a regression caused in the last Xorg update for Fedora Core 4, which resulted in some Matrox hardware to fail to initialize properly, which was introduced in the PCI config space access bugfix from the previous xorg-x11 update. The PCI config code has been updated now to handle BIOS related quirks of this nature, so this fix may also benefit users of some other brands of video hardware as well.

- A fix for a memory leak in the X server's shadow framebuffer code.

Harris lt;mharris@redhat.comgt; 6.8.2-37.FC4.48.1- Actually make sure xorg-x11-6.8.2-add-i945-support.patch gets applied to the build, as it was added before to CVS but not being used.- Build failed because 6.8.2-37.FC4.48 somehow exists already, even though it is not based on 6.8.2-48. Bump to 6.8.2-37.FC4.48.1 and try again.
